Here is another piece of information.

Previously we were using the operating system timer functionality to drive charts but that is a low priority message. This is from the Microsoft documentation:
The WM_TIMER message is a low-priority message. The GetMessage and PeekMessage functions post this message only when no other higher-priority messages are in the thread's message queue.

Now the charts are driven with a normal priority message that when received, is followed through on. Sierra Chart does not ignore these messages whereas with OS timer messages they are low priority and when there was more than one of them in the queue for a particular chart, they were all discarded and only one of them followed.
